Display Boot
After a short delay, the Gasguard 2 title screen will be displayed as depicted on the left of Figure 53.
Whilst the GG2 title screen is shown (approx. 6s) the detector is powered on and the communications
protocols will be initialised. GG2 displays have a power-up slot assigned to them based on the serial
number, there are 50 slots of 100ms each. This feature reduces the power-up impact on a power supply
with multiple devices connected. After this, the display will then attempt to establish communications with
an attached GG2 Detector (right of Figure 53).

GG2 Detector initialisation
Once the display has made a successful connection with the GG2 Detector the initialisation period of 60s
will begin. During the initialisation period, the screen controls are locked and the gas reading is not
displayed. The countdown timer shown on this screen may take a few seconds to appear due to the time
required to initialise communications with the detector.
